Overview

The PDA-LH series light/horn accessory can be connected to select Precision Digital meters to provide better visibility and control of alarm conditions. It is available in three different light configurations and each comes with a built-in 85 dB horn.

The first light option is a single color light in either red, green, yellow, blue, or white. The second light option is a user selectable light with five color options in either red, green, yellow, blue or white. Simply connect the appropriate wire to display the desired light color. The third option is a light stack with red, yellow, and green lights that can turn on independently.

The light can be wired to flash (not available on PDA-LH5C) or stay steady on. Both the light and horn can be controlled independently of each other using separate relays on the meter, and may be reset in a variety of ways based on the connected meter's relay reset capabilities.

The PDA-LH light/horn is IP65 rated, making it suitable for outdoor applications and has an operating temperature range of -40 to 40°C (-40 to 104°F).


PDA-LH Series

Power Options

Precision Digital meters with an internal transmitter power supply can provide up to 200 mA to power the transmitter and other devices including the PDA-LH series light/horn. See Specifications for details on power consumption.

If a meter connected to the light/horn does not have an internal transmitter power supply or more power is required than the meter provides, then consider the PDA1024-01 24 VDC transmitter power supply.

Control Capabilities

The PDA-LH light and horn can be controlled independently of each other using separate relays on the Precision Digital meter they are connected to. These relays can be programmed for automatic or manual reset action to satisfy a wide variety of audible and visual alarm applications.

A front panel button (F3 or Ack) on the meter can be used to silence the horn. Additionally, meters with a digital input can have a PDA-BUTTON momentary pushbutton or PDA2360 control station wired in to remotely control the light/horn such as resetting, acknowledging, or silencing an alarm (Not suported on SuperNova meters).

Connections

PDA-LH Models

Connections shown for a red light model. For other PDA-LH models, the red wire is the color of the light. Connect the red and black wires for a Steady On light and red and gray wires for Flashing light.

PDA-LH5 Connections

PDA-LH5C

Connect the LED color to the plus supply and the black wire to the minus supply to turn the LED on. Be aware of limitations for applications requiring different color lights for different alarm conditions.

PDA-LH3LC-RYG Connections

PDA-LH3LC-RYG

Connect the LED color to the plus supply for a Steady On light and LED color and gray wires to the plus supply for Flashing light. The black wire should be connected to the minus supply.

Applications

There is a wide variety of ways these light/horn devices can be controlled by Precision Digital meter's relays to satisfy visual and audible alarm applications. Feel free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.

PDA-LH Models

PDA-LH Wiring
ProVu meter with internal transmitter power supply connections shown

The PDA-LH models are the simplest devices in the series and are made up of a single-color light and horn. A typical way to use the PDA-LH is to program the meter so that the horn can be silenced at any time via a button connected to the meter's digital input or via the F3 or Ack front panel button, and the light to reset automatically when the alarm clears:

PDA-LH5C

PDA-LH5C Wiring

The PDA-LH5C shows one color at a time and the light color (red, green, yellow, blue or white) is determined by which wires are connected to power through the meter’s relays. A typical application for the PDA-LH5C might involve lighting up the red light to indicate high and low alarms and the green light to indicate everything is OK using a Precision Digital meter's four internal relays:

PDA-LH3LC-RYG

The PDA-LH3LC-RYG can light up red, yellow or green lights as determined by which wires are connected to power through the meter's relays. A typical application for the PDA-LH3LC-RYG (and the default factory setting) might involve lighting up the green light to indicate everything is OK, the yellow light to indicate a High warning, and the red light to indicate a High alarm. The Horn will also sound at both the Warning and High alarms and can be manually reset at any time via a button connected to the meter's digital input or via the F3 or Ack front panel button:

Power

Power Required24 VDC
Transmitter Power SupplyPrecision Digital meters with an internal transmitter power supply can supply up to 200 mA to power the transmitter and other devices including the PDA-LH series light/horn. The following tables illustrate how much power is required to power various light colors and the horn.
PDA-LH and PDA-LH5C Models
ColorPower Required
Red17 mA
Green15 mA
Yellow23 mA
Blue15 mA
White42 mA
Horn20 mA
Example:
17 mA (Red Light) + 20 mA (Horn) = 37 mA total current needed from the 200 mA supply. Available current = 163 mA
PDA-LH3LC-RYG Model
ColorPower Required
Red34 mA
Green29 mA
Yellow33 mA
Horn38 mA
Example:
33 mA (Yellow Light) + 38 mA (Horn) = 71 mA total current needed from the 200 mA supply. Available current = 139 mA
External Power SupplyIf a meter connected to the light/horn does not have an internal transmitter power supply or more power is required than the meter provides, then consider the PDA1024-01 24 VDC transmitter power supply.
